A printing press is a mechanical device for applying pressure to an inked surface
resting upon medium (such as paper or cloth), thereby transferring an
image. The mechanical systems involved were first assembled in Germany by
the Goldsmith Johannes Gutenburg around 1440, based on existing screw-
presses used to press cloth, grapes, etc. and possibly prints. Gutenburg
was the first in Western Eurpe to develop a printing press. During the
Renissance era, printing methods based on Gutenburg's printing press spread
rapidly throughout first Europe and then the rest of the world. It
eventually replaced most versions of block printing, making it the most
used format of modern movable type, until being superseded by the advent of
offset printing.
Based only on uncertain descriptions of the first practical telescope, invented
by Hans Lippershey in the Netherlands in 1608, Galileo, in the following year,
made a telescope with about 3x magnification. With this improved device he
could see magnified, upright images on earth, it was now known as a terrestrial telescope,
or spygalss. He could also use it to observe the sky; for a time he was one of those who
could construct telescopes good enough for that purpose.
